KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Alle bisher bekannt gewordenen Wechselstromwecker zeigen die Anordnung, daß zwischen dem Dauermagneten und Anker ein Bindeglied eingefügt ist, das gemeinhin den Namen Ankerhalter führt. Dieser Teil des Weckers ist für den Verlauf der Kraftlinien nicht nur unnötig, sondern er wirkt in der Hinsicht sogar störend, so daß . deshalb größere Abmessungen des Stahlmagneten erforderlich sind. Die genaue Regelung des Abstandes zwischen Kern und Anker wurde dabei durch Verstellen des Ankerhalters mittels Schrauben bewirkt. Diese Regelung besitzt den Übelstand, daß mit der veränderten Lage des Ankers auch der Abstand zwischen dem Dauermagneten und dem Anker sich verändert und dadurch eine unbeabsichtigte und oft schädlich wirkende Schwächung bezw. Stärkung des Magnetismus in dem Anker herbeigeführt wird.All previously known AC alarm clocks show the arrangement that between The permanent magnet and armature have a connecting link that is commonly known as the armature holder. This part of the Weckers is not only unnecessary for the course of the lines of force, but it works in the Terms even disturbing, so that. therefore larger dimensions of the steel magnet are required are. The exact regulation of the distance between core and armature was done by adjusting the armature holder effected by means of screws. This regulation has the disadvantage that with the changed Position of the armature also changes the distance between the permanent magnet and the armature and thus an unintentional and often harmful weakening respectively. Strengthening the magnetism in the armature is brought about.
Bei dem vorliegenden Erfindungsgegenstand ist dieser Übelstand dadurch beseitigt, daß der Dauermagnet an seinem oberen Ende zur Aufnahme der Ankerlagerung eine Biegung erhalten hat. Außerdem besitzt der Dauermagnet an seinem unteren Ende eine winkelförmige Umbiegung mit der Einstellschraube zum Verschieben des Dauermagneten und somit des Ankers.In the present subject matter of the invention, this drawback is eliminated in that the permanent magnet has a bend at its upper end to accommodate the armature bearing had received. In addition, the permanent magnet has an angled at its lower end Bend with the adjusting screw to move the permanent magnet and thus the armature.
Der Dauermagnet α trägt an seinem oberen Ende die Umbiegung b mit einer Lagerschraube c, welcher eine zweite Lagerschraube d gegenübersteht. Beide Schrauben dienen dem Anker e eines Elektromagneten/ zum Lager. Das untere umgebogene Ende g des Magneten α durchdringt eine Differenzialschraube /2, durch welche der Magnet auf- und abwärtsbewegt werden kann, wie aus den beiden Figuren der beiliegenden Zeichnung zu ersehen ist.The permanent magnet α carries at its upper end the bend b with a bearing screw c, which faces a second bearing screw d. Both screws serve the armature e of an electromagnet / to the bearing. The lower bent end g of the magnet α penetrates a differential screw / 2, through which the magnet can be moved up and down, as can be seen from the two figures of the accompanying drawing.
